Term	Kind	Topic	What it is
Cell Isolation	pattern	Bulkheads & Isolation	Bulkheading at the level of a complete system copy, so that any failure — including ones nobody predicted — is contained to the customers assigned to one cell.
Thread Pool Isolation	pattern	Bulkheads & Isolation	Giving each downstream dependency its own pool of threads or permits, so one slow dependency cannot consume the capacity needed to serve everything else.
